... heat transfer hydrophobic surface phase change thermal management Average temperatures are based on the thermocouple readings at the planes x a and x b . In Figs. 9( a ) and 9( b ) , the deviations of local temperatures are displayed as dimensionless values. In both cases, the trends...

...Abdullah Al-Sharafi; Bekir S. Yilbas; Abdullah Al-Zahrani Enhancement of droplet heat transfer on a hydrophobic surface is examined via introducing the fin-like structures inside the droplet without altering the wetting state of the surface. A solution crystallization of polycarbonate surface...

... are microfabricated on both a bare and a Teflon-coated silicon substrate to serve as nucleation sites. The bubble departure diameter is observed to be almost 3 times larger and the growth period almost 60 times longer for the hydrophobic surface than for the hydrophilic surface. The waiting period is practically zero...
